WALL-PAPER-CU TTIN G MACHINE.

SPECIFICATION forming part of Letters Patent No. 312,043, dated February10, 1885. Application filed January 26, 1884. (No model.)

. ming wall-paper after the paste has been applied and the paper isready to be applied to the wall; and it consists of a circular rotaryblade journaled in an adjustable slide which is arran ed to runforwardor back upon b guide above the edge to be cut or trimmed,

and in certain details of construction, all of which will be more fullyexplained by reference to the accompanying drawings, in which- Figures 1and 2 are perspective views of my device. Figs. 3 and 4 show the partsseparate.

When the paste has been applied to wallpaper, it is necessary to trimthe edges so that they will make a perfect fit, and this has usuall ybeendone with asharp knife and astraightedge. Aknife used in this mannerwill sometimes follow the grain of the board upon which the cutting isdone, and by running out of line will spoil the edge of the paper.

In my device, Ais a thin disk of steel sharpened upon the periphery, andhaving a shaft through itscenter, which turns in bearings in a block, B,having its edges channeled or grooved, as shown. These edges fit the corresponding guides, O, of the frame D, so that the block B may be movedup or down, and

thus raise or lower the cutting-disk. From the top of B a screw-threadedstem, E, extends upward and passes through a hole in the top of D, andit has nuts F, by which it 1 is adjusted up or down, so as to hold thedisk A at any desired point. Upon the bottom of the frame D are twoplates or flanges, G, and these fit one against one side and the otherin a channel, H, in the straight-edge or guide I.

The operation will then be as follows: The block B, to which the disk Ais journaled, is let down and fixed by the nuts F, so that when theframe D is placed upon the guide I the edge of the disk will run justlow enough to cut through the paper, which lies upon a board beneath.The flanges G, running along the edge and in the channel of thestraightedge, cause the cutter to run in a perfectly straight line, andprevent its being run out of the line by the grain of the board overwhich it is passing, thus insuring a perfectly straight out.

The frame D and the flanges may .be made of wood or metal, and thevertically-sliding block 13 may be made of metal or of wood, or partlyof each.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A straight-edge or guide provided with a slot, H, and having a frametongued or flanged to travel upon it, in combination with a blocksliding in a vertical channel in said frame, with a threaded stem andnuts for adjusting it up or down, and a circular sharp-edged diskjournaled in the adjustable block, substantially as herein described.

In witness whereof I have hereunto set my hand.
